The utility model aims at providing a spacing protection device of hydraulic cylinder for trailer through setting up spacing protection mechanism, can stretch out the length at hydraulic cylinder's telescopic link pole and confirm the back, fixes a position this position through spacing protection mechanism to protect hydraulic cylinder with the help of spacing protection mechanism's holding power.
In order to achieve the purpose, the utility model provides a hydraulic cylinder limit protection device for trailer, include the hydraulic pressure gooseneck of constituteing by link and gooseneck roof beam, the link with rotate through hydraulic cylinder between the gooseneck roof beam and connect, the link with still be connected with limit protection mechanism between the gooseneck roof beam.
Preferably, the cylinder body of the hydraulic cylinder is rotatably connected with the connecting frame through a cylinder base, a first pull rod base is fixed on the connecting frame above the cylinder base, the first pull rod base is rotatably connected with one end of an adjusting pull rod, a plurality of positioning holes which are horizontally and linearly arranged are formed in the other end of the adjusting pull rod, a positioning pin penetrates through the positioning holes to be connected with the top end of a second pull rod base in a positioning mode, and the bottom end of the second pull rod base is rotatably connected with a telescopic rod of the hydraulic cylinder;
the adjusting pull rod is arranged in parallel with the hydraulic oil cylinder.
Preferably, a hanging ring is fixed at one end of the adjusting pull rod, which is close to the positioning hole.
Preferably, the first pull rod base, the adjusting pull rod and the second pull rod base are made of cast iron materials with painted surfaces.
Therefore, the utility model adopts the above structure's the spacing protection device of hydraulic cylinder for trailer through setting up spacing protection mechanism, can stretch out the length at hydraulic cylinder's telescopic link pole and confirm the back, through this position of spacing protection mechanism location to protect hydraulic cylinder with the help of spacing protection mechanism's holding power.
The technical solution of the present invention is further described in detail by the accompanying drawings and examples.
Drawings
Fig. 1 is the utility model discloses an embodiment is a trailer with spacing protection device of hydraulic cylinder's schematic structure diagram.
Wherein: 1. a gooseneck beam; 2. a second tie rod base; 3. a hydraulic cylinder; 4. a connecting frame; 5. a first tie rod base; 6. adjusting the pull rod; 7. positioning holes; 8. a lifting ring.
Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the present embodiment.
Fig. 1 is the embodiment of the utility model provides a trailer is with spacing protection device of hydraulic cylinder's schematic structure diagram, as shown in fig. 1, the utility model discloses a structure, include the hydraulic pressure gooseneck of constituteing by link 4 and gooseneck beam 1, rotate through hydraulic cylinder 3 between link 4 and the gooseneck beam 1 and connect, still be connected with spacing protection mechanism between link 4 and the gooseneck beam 1.
Specifically, a cylinder body of the hydraulic cylinder 3 is rotatably connected with a connecting frame 4 through a cylinder base, a first pull rod base 5 is fixed on the connecting frame 4 above the cylinder base, the first pull rod base 5 is rotatably connected with one end of an adjusting pull rod 6, a plurality of positioning holes 7 which are horizontally and linearly arranged are formed in the other end of the adjusting pull rod 6, positioning pins penetrate through the positioning holes 7 to be connected with the top end of a second pull rod base 2 in a positioning mode, and the bottom end of the second pull rod base 2 is rotatably connected with a telescopic rod of the hydraulic cylinder 3;
the adjusting pull rod 6 and the hydraulic oil cylinder 3 are arranged in parallel, so that after the extension distance of the telescopic rod of the hydraulic oil cylinder 3 is determined, the positioning pin penetrates through the second pull rod base 2 and penetrates into the positioning hole 7 in the adjusting pull rod 6, the position of the telescopic rod is positioned, the supporting force of the adjusting pull rod 6 is used for sharing the stress of the hydraulic oil cylinder 3, and the effect of protecting the adjusting pull rod 6 is achieved.
Preferably, a hanging ring 8 is fixed at one end of the adjusting pull rod 6 close to the positioning hole 7, so that the adjusting pull rod 6 can be conveniently adjusted when the positioning pin is inserted, the hole formed in the second pull rod base 2 is aligned with the corresponding positioning hole 7 in the adjusting pull rod 6, and the positioning pin can be conveniently inserted.
Preferably, the first pull rod base 5, the adjusting pull rod 6 and the second pull rod base 2 are all made of cast iron materials with painted surfaces, and manufacturing cost is low.
Therefore, the utility model adopts the above structure's the spacing protection device of hydraulic cylinder for trailer through setting up spacing protection mechanism, can stretch out the length at hydraulic cylinder's telescopic link pole and confirm the back, through this position of spacing protection mechanism location to protect hydraulic cylinder with the help of spacing protection mechanism's holding power.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the technical solution of the present invention can still be modified or replaced by other equivalent means, and the modified technical solution can not be separated from the spirit and scope of the technical solution of the present invention.
